Cannot Force JavaFX Printer to Print HTML in Color #1248

Open Vzor- opened 8 months ago

System: Windows 10

While testing #1247, I found that a printer which had been set to 'Black & White' in the device driver could not be told to print in color when printing from HTML. This JavaFX behavior is inconsistent with AWT printing, such as PDF/Image.

To reproduce:

Set up PDFCreator, or any printer with the Preferences>Paper/Quality>Color setting.
Note: 'Microsoft Print to PDF' does not have the color setting, so it will not work in this test.
Set color to 'Black & White'
Start QZ tray
In sample.html, select pixel print and change 'Color Type' to Color
Select 'Print HTML'

The issue seems to stem from this line https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/javafx/print/JobSettings.java#L910 When the printer is set to 'Black & White', 'Color' is not considered to be supported.

Thanks for documenting this @Vzor-. Can you provide a small reproducible example to provide to Gluon for an upstream bug report?
